How to Space Your Divided Hollyhocks for Optimal Growth

by

Hollyhocks are a charming addition to any garden, known for their tall spikes and vibrant flowers. Proper spacing when dividing and planting hollyhocks is essential to ensure healthy growth and abundant blooms. This guide provides practical tips on how to space your divided hollyhocks for optimal growth.

Understanding Hollyhock Growth Habits

Hollyhocks are biennial or short-lived perennials that produce tall flower spikes. They prefer well-drained soil and full sun. When dividing mature plants, it’s important to consider their mature size to prevent overcrowding and promote air circulation.

Timing for Dividing Hollyhocks

The best time to divide hollyhocks is in early spring or late fall, when the plant is not actively flowering. This allows the divided plants to establish roots before the growing season. Avoid dividing during hot summer months to prevent stress.

Steps for Proper Spacing

  • Prepare the soil: Ensure the planting area has well-drained, fertile soil enriched with compost.
  • Dig up the plant: Carefully lift the hollyhock clump, keeping the root ball intact.
  • Divide the roots: Use a sharp knife or garden spade to separate the clump into smaller sections, each with roots and shoots.
  • Choose the right spacing: Space the divided plants about 18 to 24 inches apart to allow for growth and air circulation.
  • Plant the divisions: Plant each section at the same depth as it was growing before, firming the soil around the roots.

Optimal Spacing Recommendations

For most hollyhock varieties, spacing the divided plants 18 to 24 inches apart provides enough room for their tall growth and prevents diseases caused by poor air circulation. If you have a larger variety or want a denser display, you may increase the spacing to 30 inches.

Additional Tips for Healthy Hollyhocks

  • Ensure adequate watering, especially during dry spells.
  • Apply mulch around the plants to retain moisture and suppress weeds.
  • Support tall varieties with stakes or cages to prevent falling over.
  • Remove dead or diseased leaves to improve air circulation.
  • Fertilize with a balanced, slow-release fertilizer in early spring.

Conclusion

Spacing your divided hollyhocks correctly is key to achieving healthy plants and vibrant blooms. By following proper timing, spacing guidelines, and maintenance tips, you can enjoy a stunning hollyhock display year after year.
